I FLYING MACHINE Application filed. December 12, 1931. Serial 1T0. 580,693, 1

The present invention relates to new and useful improvements in {flying machines, andmore particularly itpertains to flying machines of thetypeknown as sail planes and gliders. y i

It is one of the primary objects of the present invention to provide means whereby a flying machine may be sustained in flight atleast temporarily under conditions where upwardly directed air currents are not present.-

It is a further object of the invention-to provide a flying machine of the sail plane or glider type with manually operatedmeans to sustain the plane in flight.

It is a still further object of the invention so to construct the device that it may be readily operated manually by the occupant of the machine.

With the above and other objects in view, reference will be had to the accompanying drawings wherein;

Figure 1 is a plan view of a sail plane or glider constructed in accordance with one form of the present invention,

Figure 2 is a view in front elevation thereof,

Figure 3 is a vertical sectional view thereof on an enlarged scale,

Figure 4 is a vertical sectional view on a still further enlarged scale showing a portion of the operating mechanism,

body of the plane, and 11 designates the supporting wing thereof. I In accordance with the present invention I provide auxiliary wings '12 and these wings are relatively smaller than the sup porting wing 11. The auxiliary wings 12 are mounted upon brackets or the like. 13 which are rigidly attached as at 14 to the supporting wing 11 at equal distances from the longitudinal axis of the body 10 and upon which the auxiliary wings 12 are mov able as illustrated by dot and dash lines in Figure 3. i

The auxiliary wings 12 are adapted to function in the nature of propelling wings in that their movement tends to maintain the lane in theair.

eans is provided to operate the auxiliary wings 12, and in the present illustration of the invention this means consists of cables 14 which pass around pulleys 15, and which areattached to an operating lever or stick 16 mounted in the cockpit ofthe body 10 ina position closely adjacent the seat 17 upon which the occupant sits.

In Figure 4 I have shown one means of mounting the auxiliary wings in such a manner that they may be moved as illustrated by the dot and dash lines in Figure 3, and in thisform of the invention the bracket 13 is provided on its upper end with a portion 20. Carried upon the interior of the member 20, there is a tubular member 21 which is threaded as at22 into an internal flange of the member 20. Slidably mounted in the member 21 which forms the bearing therefor, there is a rod 24 andsecured to the/upper end of the rod 24 there is abracket or the like 25 which in turn is secured to one of the ribs orstruts 26 of theauxiliary wing 12. Surrounding the member 24 and having its lower end resting upon the flange 22, there isa coil spring 27 and this coil spring serves to maintain the auxiliary wing in its extended or full line position shown in Figure3. The spring 27 as heretofore stated is adapted to maintain the auxiliary wing 12 in its extended position, and during operation, movement of the stick 16 will through the medium of the cables 14 pull the auxiliary wing 12 downwardly to the position in which the wing is shown in dot and dash lines in Figure 3 and place the spring 27 under compression. Movement of the stick in the opposite direction will permit the spring 27 to move the auxiliary wing to the extended position due to slack produced in the cables 14. v

In the described form of the invention, the relatively small auxiliary wings are placed midway between the ends of the main supporting wing. In Figure 5, however, I have illustrated a slightly modified form of the invention in which two relatively small auxiliary wings 30 are placed closely together at the center of the ship, and are divided by means of a vertically disposed vane or the like 31. These wings 30 are mounted in the same manner as heretofore described and are operated by means of cables or the like 32 which pass around suitable pulleys and are attached to a stick or the like 33 which is of the same general type as the stick 16 heretofore described.

In Figure 6 I have illustrated a still further modified form of the invention, and in this form of the invention there is but one auxiliary wing designated 35 in the drawings. This wing is mounted on two standards 36 of the construction heretofore described, and operated by a single cable 37 in the same manner heretofore described. This form of the invention differs from those heretofore described in that a single wing 35 is placed substantially centrally of the ship as distinguished from a single wing on opposite sides of the center of the ship.

In Figure 7 of the drawings, there is illustrated a slightly modified form of the in Vention and its operating means, and in this form, the main supporting wing designated 50 is provided with a recess or the like 51 which conforms to the shape of the auxiliary wing 52 will be moved either into the recess 51 or extended therefrom for the purposes heretofore described.

From the foregoing it will be apparent that the present invention provides a new and novel mechanism whereby a sail plane, glider or similar flying machine which has no power may be temporarily sustained in flight when the conditions are such that the ship would not under ordinary circumstances be maintained in flight.

Vvhile the invention has been herein illustrated in its preferred form, it is to be understood that it is not to be limited to the specific constructions herein shown, and that it may be practiced in other forms without departing from the spirit thereof.

Having thus described the invention, what is claimed as new and what it is desired to secure by Letters Patent of the United States,

In a flying machine, a supporting wing, rigid brackets projecting vertically from said supporting wing at equal distances from the center thereof, propelling wings carried by said brackets in spaced relation to said supporting wing, said propelling wings being movably mounted on said brackets, manually operated means for moving said propelling wings in a direction towards said supporting wing, and resilient means for moving the propelling wings in a direction away from said supporting wing when the manual means is released.

In testimony whereof I aflix my signature.

wing 52 which auxiliary wing 52 is adapted to nest in the recess 51 when not in use. The auxiliary wing 52 is mounted upon toggle levers 54 which are pivotally connected together as at 55 and operated by a vane lever 56 which is adapted to operate the toggle lever 54 in such a manner as to-move the V auxiliary wing 52 in a direction towards or away from, the main supporting wing 50. The main wing 50 has guide rods or the like 56 -carried thereby and one'end of the levers 54 have bearings 57 which slide upon theserods 56. The opposite ends of these rods have bearings 58 and said bearings 58 slide upon guide rods 59 carried by the auxiliary wing 52. Thus as the operating lever 56 is moved, the toggle levers 54 will be expanded and contracted and the auxiliary
